Acute diarrhoea in children treated in an outpatient setting in Athens, Greece.

OBJECTIVE: To describe the epidemiology and aetiology of acute diarrhoea among children treated exclusively in an outpatient setting in Greece. METHODS: During 1999, children with acute diarrhoea who attended the emergency department of our hospital were prospectively studied. Patients requiring hospitalization were excluded. Stool specimens were tested microscopically, for bacterial enteropathogens by standard and selective medium cultures and for rotavirus and adenovirus by latex agglutination test. RESULTS: One hundred and thirty-two children (median age: 2 years) were included in the study; an enteropathogen was detected in 63 (48%) of them. Isolates included rotavirus (19 patients), Salmonella sp (12), Campylobacter sp (10), Aeromonas sp (9), enteropathogenic Escherichia coli (6), adenovirus (6), Giardia lamblia (4), Yersinia enterocolitica (2) and Shigella sp (1). Half of the bacterial cases occurred from August to October, and two rotavirus-associated peaks occurred during February and August. Acute diarrhoea caused by viruses affected exclusively children under six years of age, mainly those attending day care centres. Macroscopic blood in stools was reported only among patients with a bacterial infection. Socioeconomic characteristics were not helpful in differentiating disease due to specific enteropathogens. CONCLUSIONS: Bacterial enteropathogens account for a significant proportion of acute diarrhoea in children treated in the outpatient setting in Greece. Rotavirus is also a frequent cause affecting mostly younger children and those attending day care centers. The presence of blood in stools and the seasonality of bacterial infections may enable their presumptive diagnosis.

Endocrine correlates of male breast cancer risk: a case-control study in Athens, Greece.

We studied the relation of certain endocrine-related variables among 23 cases of male breast cancer and 76 apparently healthy male controls. There were significant inverse associations with smoking (P = 0.03), birth order (P = 0.02) and reported frequency of orgasms in later life (P = 0.0004). The study provides strong indirect evidence that endocrine factors are important in the aetiology of male breast cancer.

Epidemiology, clinical course and impact on hospitalization costs of acute diarrhea among hospitalized children in Athens, Greece.

The aim of this study was to describe the etiology, morbidity and hospitalization costs associated with acute diarrhea among hospitalized children in Greece. During 1999, 294 hospitalized children (median age 1 y) with acute diarrhea were prospectively studied. Bacterial and viral enteropathogens were detected in 100 (34%) and 37 (12.5%) patients, respectively; 17 (6%) patients had mixed infections. Isolated agents included Salmonella spp. (43 patients; 15%), rotavirus (32; 11%), Campylobacter spp. (26; 9%), enteropathogenic Escherichia coli (16; 5.5%), Shigella spp. (11; 4%), Aeromonas spp. (7; 2.5%), adenovirus (6; 2%), Yersinia enterocolitica (6; 2%), enterohemorrhagic Escherichia coli (2; 0.5%) and Giardia lamblia (1; 0.5%). Of the patients with bacterial infection, 70% were admitted between April and September 1999. A rotavirus-associated peak was noted in March. Patients with a bacterial infection were hospitalized for longer periods than those with viral infections. It is concluded that bacterial enteropathogens account for one-third of admissions due to acute diarrhea among children in Greece and are associated with significant hospitalization costs. Rotavirus is also a frequent cause of acute diarrhea necessitating hospitalization.

Detection of arrhythmias in a representative sample of the Athens population.

The prevalence and type of arrhythmias has been studied in a representative sample of 2000 Athenians, aged 18-81 years, who underwent exercise testing on a treadmill according to the Bruce protocol. It was found that 121 persons (mean age 55.7 +/- 14.9 years, 31% greater than 65 years), exhibited arrhythmias on the ECG during either the exercise or the 10 min period following it (prevalence 6.05%). The age-adjusted prevalence was 6.7%, that is 7.1% for men and 6.2% for women. Out of these 2000 Athenians 43 (2.15%) exhibited unifocal VPCs (23 with greater than or equal to 3 VPCs min-1 and 20 with less than 2 VPCs min-1), 10 (0.5%) multifocal VPCs (6 with single and 4 with paired VPCs), 12 (0.6%) bigeminy, 25 (1.25%) supraventricular PCs, 16 (0.8%), supraventricular PCs and VPCs, 5 (0.25%) respiratory arrhythmia, 3 (0.15%) coronary sinus rhythm, 3 (0.15%) atrial fibrillation, one (0.05%) ventricular tachycardia, 2 (0.1%) first-degree and one (0.05%) second-degree AV block. In 32 out of those 121 persons arrhythmias were present also at rest (26.5%). Ventricular premature contractions and/or supraventricular PCs were the most common type of arrhythmias (87.6%). The majority of VPCs (69%) and supraventricular PCs (80%) appeared during the 10-min observation period following exercise. Coronary heart disease and valvular heart defects were found more frequently among the participants with than those without arrhythmias at exercise testing (19.83% vs. 8.83% and 2.48% vs. 0.27%, respectively).

Antimicrobial susceptibility patterns of Campylobacter jejuni strains isolated from hospitalized children in Athens, Greece.

The antimicrobial susceptibility of 129 Campylobacter jejuni strains, isolated from hospitalized children with gastroenteritis, to five antimicrobials, including nalidixic acid, ciprofloxacin, erythromycin, ampicillin and co-amoxiclav, was determined. Isolates belonged to two time periods: group A contained strains isolated in 1987-1988; and group B 1998-2000. Antimicrobial susceptibility patterns differed significantly between the two groups with respect to quinolones, with an increase in the percentage of resistant strains in group B (30.6% versus 0% in group A), whereas erythromycin, ampicillin and co-amoxiclav were effective drugs in both groups.
